Because of the word "cumulative". What that means is that the height of the graph for any value (X=x) is the number (or proportion) of observations that were less than or equal to the value x.
Now consider the cumulative value of the graph for a value of X which is bigger than x. All the previous observations were ≤ x and so they will be ≤ the newer, larger value. So the height of the cumulative graph cannot decrease. It may increase if there are any observations whose value was between x and the new value.

A pie chart or composite bar graph.
What does a vertical straight up and down line on a graph mean?
y axis
Where is the growth rate slowing down in the graph shown above?
point C
Usefulness of cumulative frequency curve?
It will show you whether it is a constant rate or if it speeds up or slows down.
How do you work out a cumulitive frequency?
in a maths question, you have a table. you add up the frequency column, but every time you add something, you write it down, e.g. frequency cumulative frequency 1 1 5 6 3 9 6 15 and so on :)
What is a continuous line graph?
a continuous line graph is a graph that is similar to a broken line graph but it always grows higher and higher it never goes down. e.g. age
What is an x-coordinate?
it is a down on the graph
If the line on a speed graph goes down this means?
you are slowing down
Explain how the graph of fx ln x be used to graph the function gx ex -1?
graph gx is the reflection of graph fx and then transformed 1 unit down

Is a vertical line up or down?
up and down it is the y axis on a graph
What describes how to translate the graph y x to obtain the graph of y x - 6?
To translate the graph y = x to the graph of y = x - 6, shift the graph of y = x down 6 units.
How do you draw a horizontal bar graph?
up and down
What is the frequency spectrum?
Scroll down to related links and look at "Frequency spectrum - Wikipedia"
In GSM which frequency uplink or downlink is greater?
Up-link freq is higher than down-link freq in GSM You answer is wrong Correct answer is that, down-link frequency is greater than the up-link frequency in GSM. Up-link Frequency = 890 MHz - 915 MHz Down-link Frequency = 935 MHz - 960 MHz
